Application filed April 13,1912. Serial No. 690,565.

To all whom it may concern Be it known that I, BEHNHARDT HENRIK- sox, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in BoringMachines, of which'the following isa specification.

My. invention relates to boring machines, and the object thereof is to provide a simple, efiicient and reliable machine for boring the bearing surfaces of bearings, more particularly (but not necessarily) the babbitt of bearings such as car brasses.

My machine is adapted to bore out the Babbitt metal in a simple and convenient manner and to perform the work with great accuracy.

The various features of advantage and utility in my machine willbe apparent from the description hereinafter given.

In the drawings Figure 1 is a plan View of my machine; Fig. 2v a side elevation thereof; Fig. 3 a detail plan of a portion of the machine; Fig. 4 a vertical section on .the line 44 of Fig. 1-; 5 a ,vertical section on the line 5-5 of Fig.1; Fig. 6 a vertical section on the line 6'6 of Fig. 1;

' Fig. 7 an elevation of one of the operating connections of the machine; Fig. 8 a section on the line 'S8 of Fig. 7; Fig. 9 a perspective view of a car brass; and Fig.- 10 a detail view of one of the adjusting washers or collars.

In the present instance I have, for the sake of a clear and definite disclosure of my invention shown the same as embodied in a machine constructed and arranged to bore out car brasses used in journal boxes ofrailway cars but it will be understood that my invention is not to be limited to such par ticular use but that by modifying the form of several of the parts of the machine, it may be as well used for boring out other kinds of bearings. -Referring to the particu-' lar machine illustrated in the drawings the same is provided with a bed plate 1 supported by legs 2 and a plate 3 supported above such bed plate and arranged in a horizontal plane. Upon-the face of this plate 3 are secured in longitudinal alinement two forms or pads 4 and 5, which are similar to each other with the exception that the pad 5 is the larger to the extent of the cut made by the cutter as hereinafter described. These pads are stationary and "partake of the form of the bearing face of the bearing which is here shown as a car brass indicated at 6.

In suitable bearings 7 and below the plate 3-is arranged the cutter arbor or shaft 8 extending longitudinally of the machine. This shaft is driven in any suitable manner as by means of the pulley 9. To this shaft is secured a cutter device comprising a head 10 provided with the series of radial slots in which the cutters 11 are mounted, and an adjusting wedge-shaped collar 12 encircling the hub portion 10 of the cutter head and adapted to engage the inner ends of the cutters to determine the ters and to thereby determine the depth of cut in the boring operation, Figs. 5, and 6. As shown in Figs. 1 and 2 this cutter is arranged between the two pads 4 and 5 and 1113.11 opening 3 in the plate 3. More over, the axis of this cutter is in the same vertical plane as the longitudinal axes of the two pads 4 and 5. Initially, the car brass is placed upon the pad 4 and is fed to the left, Figs. 1, 2 and 3, over the cutter and upon the other pad 5. The means for holding the car brass during this boring operation and for so feeding the same, consists of a plate 13 whose under surface, in this particular instance, corresponds with is pivotally connected at 14 to a swinging hand-nperated lever 15 which is adapted to be grasped andoperated by the attendant. This lever is arranged to be moved in a horizontal direction from right to left so as to feed the car brass in the manner already outlined, and in the present instance the means for so feeding the lever are adapted to be brought into operation onlywhen the the top-surface of the car brass. This plate lever is in its operative position, that is,

when its plate 13 is pressed upon the work.

Describing the operating means herein shown, the same includes a driving shaft 16 which runs constantly as. long as the cutter is rotated, in view of the intermeshing driving gears 17 and 18 on the shafts 8 and 16 respectively; This driving shaft 16 is mounted in suitablebearing brackets 19 on the main frame and is in the form of a screw shaft with the screw threads 16 intermediate its length. Ootiperating with this screw shaft is a nut 20 of the peculiar form clearly shown in Figs. 7 and 8, such nut having an enlarged opening 20 receiving the screw shaft and also having at the ing screw mediate its This nut, arm and sleeve are end: of the machine,

lower side of such opening screw threads 2O which areadapted to engage the correspondthreads of the shaft 16. Thisnut is provided with an arm 21 havlng interlength and toward its upper end 21' adapted to receive an end of the This arm terminates at its upper a slot lever 15.

end in a sleeve 22 having an opening 22" which is elongated in a vertical direction.

in the present instance made in a single piece and the same constitutes an operating link or connection between the lever 15 and the driving shaft 16. The sleeve 22 fits over guide rod or shaft 23 extending horizontallyabove-and parallel with the drive shaft 16, the ends of the same being secured to between the bosses 28 and 29 on the plates the posts 24 rising machine. I

The operation of my machine when used for the boring of car brasses as herein shown is as follows: The car brass is placed upon from the frame of the I the pad 4: and the lever 15, which-has here} tofore been supported by the rest 25 near one is, together with its brought to a position car brass. It will be underthe lever 15 is in its-inacthe rest 25, the connecting the parts 20, 21 and 22, is inits lowermost position with the nut 20 out of operative relationship with the screw shaft 16L However, when the lever and its carrier or plate 13 are directly over the stood that when tive position. on

wit-h the operator pressing downwardlywith some force, the nut 20 is-raised upwardly by the pivotal action of'the lever 15 to a position of encarrier will be fed to the left, Figs. 1, 2 and 3. In-this particular instance the left-hand edge of the plate 15 will engage the usual flange portion 6 cutter, during which operation the attendant or operator presses down free endof the lever 15.

ing surface of the car brass fits rather accuthe pad 4 and after it has been bored out by the cutter it will be fed along over the other pad 5 which will accurately fit such bearing after being bored, such pad 5 being larger than the pad 1 to the extent After the bearing-has been fed entirely past the cutter the operator swings the lever 15 upwardly thereby lowering the link connection and disconnecting-the latter from the screw shaft, at which time such link will be supported by the guiderod23 and the operator can then easily and freely slide said parts back to the right to initial position an a repetition of the operation ea, scribed. The two pads and-5 are remov 35 able from the top plate in order that forms brought to the dethe screw shaft, with the re- 40 suit that the connecting link, lever 15 and its .upon WhlCh the work is 1n1t1ally placed and of the car brasswhich will 45 thereby. be fed positively to and over the upon the outer or The inside or bearside of. the padyacarrier adapted to fit upon and engageQtheiwork, and means'for actu- 1 "ating the carrier for feeding theg'work, from or pads of other sizes or shapes maybe substituted according to the part1cularcharac-; ter of bearing being operated upon, and

likewise the plate 13 is made removable from the lever 15 in order that other sizes "or shapes of plate may be substituted, according to the work or bearing being operated upon. I prefer the replacement or substi? tntion of pads according to the shape and size of the particular bearings being oper ated' upon but some range of adjustment? may be secured by raising or lowering the top plate 3, which adjustment may. be -provided for in the following manner. -The plate 3 is mounted upon and spaced above the plate 1 by means of the bolts 26 and the collars -o-r washers27 which are interposed 1 and 3 respectively, the bolts 26 passing through the collars and the said bosses as shownin Figs. 2 and .4. These collars-are made in sets of difierent sizes orheights with the result that any desired degree of spacing between the two plates 1" and 3 may be secured by insertinga set of collars of the desired height. In order to facilitate the removal and insertion of these collars each is provided with a side opening orslot .27", as

clearly shown in'Fig. '10. The effect of-raising or lowering the top plate has the effect of correspondingly raising or lowering the. pads 4 and 5.
